Rated 5 out of 5 stars

The download button in TB3 missing is missing for RSS feeds with attachments.
It's there for emails, but not for RSS feeds. This used to work in TB6.

Thank You

This review is for a previous version of the add-on (1.0.0.1). 

It is now (1.0.0.3) visible again, but disabled (Thunderbird does that, as this is also in default theme - don't ask me why). Thanks for your report!

UPDATE: The disabled button is a TB 7 bug, a fix is available at https://addons.mozilla.org/en-US/thunderbird/addon/rss-attachment-fix/
